by virtue of inbounds GEPs that preclude a null pointer. This is a very common pattern in the code generated by std::vector and other standard library routines which use allocators that test for null pervasively. This is one step closer to teaching Clang+LLVM to be able to produce an empty function for: void f() { std::vector<int> v; v.push_back(1); v.push_back(2); v.push_back(3); v.push_back(4); } Which is related to getting them to completely fold SmallVector push_back sequences into constants when inlining and other optimizations make that a possibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169573 91177308-0d34-0410-b5e6-96231b3b80d8 |
